TALKING MACHINE.

Application filed December 3, 1920.

Machines, of which the following is a speci- I fication.

My invention relates to talking machines or phonographs, and moreparticularly to the construction and arrangement of the horn andmodifier relatively to each other and to the motor board with which theycooperate.

My object is to provide a device of this character of very simple, cheapand durable construction, that will-be thoroughly effec tive inoperation.

Other and more specific objects will appear in the subjoineddescription.

An important feature of my invention consists of a horn provided at itsinner open end with means for securing it to the motor board, said meansconsisting of two flat bars disposed parallel to each other and securedat their lower edges to opposite sides of the extreme upper end of thehorn, and bent outwardly at their outer ends to form openings or holesfor the reception of screws for securing the horn to the motorboard,said bars being of suflicient width to provide room between the top ofthe horn proper and the motor-board for the insertion of a modifier ordamper to regulate the volume of sound delivered by the horn.

The invention consists in certain novel features of construction andarrangements of parts as will be hereinafter described and claimed,reference being had to the accompanying drawings in which Fig. 1 is aside elevation of the upper part of a phonograph embodying my invention,the cabinet and certain other parts being shown in section to moreclearly bring out the construction.

Fig. 2 is a perspective view of the frame of my horn.

Fig. 3 is a perspective of the modifier or damper.

Fig. 4 is a broken perspective showing the damper in its normal positionrelatively to the two securing bars at the inner end of the horn.

Fig. 5 shows a slightly modified form of securing bars at the upper endof the horn.

Serial No. 428,085.

Fig. 6 is a top plan view of my phonograph with the dome removed.

ig. 7 is aside elevation of the horn; and,

Fig. 8 is a bottom plan View thereof.

deferring further to the drawings, the numeral 1 indicates the cabinet;2, the dome;

3, the motor-board; 4, the motor; 5, the rec- 0rd; 6, the reproducer;and 7, the tone arm. All of these parts just mentioned are of usual orany preferred construction.

The horn of my device is formed of fabric or flexible material supportedby a wire frame, the frame usually being on the outside of the fabric.

The frame of the horn is formed of the upper and lower longitudinalwires 8 and 9 respectively, which form the four longitudinal corners, soto speak, of the horn. These wires are connected together by means ofthe substantially rectangular wire frames 10, 11, 12, 13 and 14, whichare secured at their corners by soldering or any other preferred meanstothe upper and lower corner wires 8 and 9. The rectangular frames 10 and14 are at the inner and outer ends re spectively of the horn. The topand bottom sections of the rectangular frame 14 are connected betweentheir ends to the upper and lower corners respectively of the frame 13,by means of the brace-rods 15, which rods are also secured at their endsto said parts by solder or otherwise. At the extreme outer end of thehorn the wires 8 and 9 extend outwardly slightly beyond the rectangularframe 14 to form the extension 8" and 9 respectively.

Special attention is now called to an important feature of myconstruction. At the inner end of my horn are two flat bars 16, withtheir lower edges secured to the outer and inner sides respectively ofthe rectangular frame 10, and bent outwardly at their ends into thecircular loops 17 to form the holes 18 for the reception of screws forsecuring the horn to the motor-board.

The damper or modifier 19 is received on top of the frame 10 between thetwo fiat parallel bars 16, and is adapted to move longitudinally backand forth between said bars, said modifier having a central opening 20adapted to be moved into registration with the opening 21 in themotor-board, which latter opening leads up into the tone arm 7 above themotor-board.

The modifier 19 is provided with a handle 22 which projects out throughthe side of the casing 1, and is provided with a ball or knob 23 on itsouter end.

A slightly modified form of my horn is illustrated in Fig. 5, in whichthe flat bars 16 are substituted by wires 24:, which are bent at theirends to form the round loops 25 for the reception of screws for securingthe horn to themotor-board. T his "form of the horn is for machines thatdo not have a modifier.

The flexible part of" my horn which is supported by the wire frame, is iormed 01" any desired material, such for instance. as silk, muslin,burlap, canvas, and the like; and these fabric materials may be treatedin any mrdinary or preferred way, in order to improve the quality of thetone produced or the durability oi? the horn. The horn is secured to theframe in any desired way, and usually on the inside thereof.

In operation the inner end of the horn is secured to the under side ofthe motor board 3 immediately underneath the tone arm, by means ofscrews passed up through the openings 18 of the flat bars 16; and theprojections 8 at the outer end of the horn are received in the cornersof the opening 26 in the front side of the cabinet.

The modifier is received between the inner open end of the horn and theunder side of the motor board, between the two bars l6 which hold itagainst lateral movement,

while the handle 20 extends out through a suitable opening in the frontside of the cabinet, which arrangement permits the operator of themachine to move the modifier longitudinally back and forth, to bring itsopening 20 into different degrees of registr' tion with the opening 21in the motor board.

In the modified form of the device illustrated in Fig. 5, the securingscrews are passed through the. circular loops 25. by which arrangementthe inner end of the horn is secured to the motor board without anyintervening space between.

From the foregoing it will be seen that I have provided a horn of verysimple and cheap construction, which also forms a support or housing forthe modifier.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is in device of the character described, a

horn having a supporting frame suitably secured around the outsidethereof, said frame being provided at its inner open end withtransversely disposed parallel spacing bars rigidly secured. thereto forholding the horn in spaced relation to the motor board, said spacingbars being bent outwardly at their ends into circular loops to formholes, Whereby to provide means for securing the horn to the motorboard.

In testimony whereof I affix my signature.
